Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
In accordance with column 2 of Annex IX 9.3.2 of EC 1907/2006 bioaccumulation testing in aquatic species is not required as the substance has a low potential to cross biological membranes.
Bioaccumulation of Dipentaerythrol ester of n5/iC9 acids is very unlikely because most components of the substance have a very high molecular weight (> 800 g/mol). It can be expected that the components of the substance are not bioavailable at all. Due to their hydrophobicity, it is very likely that components will adsorb to sediment and particulate matter. Furthermore, steric hindrance at passage of gill membranes or cell membranes of respiratory organs can be very important for substances that have a molecular weight higher than 500 or a molecular size larger than 9.5 A. According to the EU Technical Guidance Documents, substances with a molecular weight higher than 700 are unlikely to bioaccumulate significantly (regardless of the log Pow value).
This is outlied in a detailed expert statement by Hamwijk (2004).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
